MOLD FOB BUILDING MONOLI'I'HIG HOUSES.

Original application filed July 16, 1913, Serial No. 779,267. Dividedand this appilcation filed larch 5 1914. Serial No. 822,741.

To all whom. it may concern:

Be it known that I, FRANK D. LAMBIE, a

citizen of the United States, residing at structing monolithic concretebuildings and more specificallyjo mold frames for providing the door andwindow openings in the walls of the building during the construction ofthe same.

In my parent application, Serial No. 779.267. filed Julv 16, 1913, ofwhich application the present case is a. division, I have disclosed amold consisting of substantiallv rectangularlv-shaned exterior andinterior mold-frames which are spaced apart sufficiently to give thenecessary thickness to the concrete walls. the frames being composed ofvertically dis osed flanged lates securely fastened together. theinterior frame supporting the ceiling plates and having substantiallythe form of an inverted box, whereby the mold frames for casting onecomp ete story of the building. including a floor, is completelvassembled at the same time and the concrete mav be poured in a singlecast. If a mold of this description is used, it is necessary to provideaccess to the interior frame so that it mav be removed after the wallsand fioor of the building have set and one of the aims of the presentinvention is to provide alining openings in both an exterior andinterior mold frames which are adapted to be used for this purpose andwhich are of a size and so located that they can be used to form thedoor and window openings when the walls are cast.

Another object of the invention is the provision of a mold frame inwhich the window frame proper may be utilized as a part of the mold toform the openings in the wallframes through which free access may be hadto the interior mold frame, which window frame remains embedded in theconcrete after the same has been cast.

A still further object of the invention is to provide a concrete windowsill offset from the main surface of the wall which is formedsimultaneously with the casting of Specification of Letters Patent.

the latter and thereby adds to the attractiveness of the building.

With these and other objects .in view, my invention consists of thecombinations and constructions which will be hereinafter set forth inthe specification and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a front elevation of oneexterior face of a mold embodying the features of mv invention; Fig. 2is a transverse section through the interior and exterior mold framesshowing the window construction; Fig. 3 is a transverse section throughthe mold showing the door construction; and Fig. 4 is a transversehorizontal section of a detail of the window mold frame on an enlargedscale.

As disclosed in the parent application hereinbefore referred to. theexterior mold frame is composed chieflv of standard wall plates 1 whichare vertically disposed and are provided with oroiecting flanges flushwith their edges. These plates or panels are relatively long and narrowand in thebest practical constructions are generallv of suffic entheight'to complete one story of the building. At interva s in the sideflanges of the panels are unifo mly spaced square apertures or holes. whch register when the plates are arranged with their flanges abutting andtheir surfaces flush.

Fastening devices consisting of clips 2 provided with shanks'havingrectangular slots therein pass through the registering apertures andwedges or keys are driven into the rectangularslots which draw theflanges of the plates close together to form a water-tight jointpreventing the formation of ridges on the surface of the wet concreteduring the casting operation. Each of the standard plates or panels isprovided with L-shaped locking notches 3 in their side flanges neartheir upper and lower ends. respectively, which notches receive theliner locks 4 which lock the panels together with their surfaces flush.and which will also prevent any relative lateral movement of the platesbefore or while the concrete is being poured, thereby avoiding anyirregularities or defects in the walls of the house. Secured to theupper ends of the wall plates or panels are belting course plates 5, theexterior frame being supported against lateral displacement by tie-rods6 which pass through the belting course plates to opposite sides of theframe and hold it rigidl inn-position, a portion of one of said ros'being shown in Fig. 2. The interior frame is also composed of aplurality of-vertically-disposed standard plates or panels 1 which areclipped and locked together by liner locks in the manner which has beendescribed; the plates in the interior frame being arranged in exactalinement with corresponding plates of the exterior frame. The upper rowof liner locks 4 support eyebeams or channel irons 7 carr ing ceilingplates 8 which are also standar plates, and which are supported withtheir surfaces substantially flush with the top flanges of the wallplates. These ceiling plates are adapted to sustain the layer ofconcrete forming the floor of the next story.

Where a door openin is to be provided in the wall: of the bail ing, aplurality of standard vall plates or panels are omitted from both theinterior and exterior frames to provide an opening of the desired size,the edges or flanges of the plates facing the opening being in exactalinement, since all of the plates in both the exterior and interiorframes are so arranged. Horizontally-dispcsed flanged plates 10 arefastened by clips 2 to. the side flanges of the wall plates of both theinterior and exterior frames at the upper ends of the same with the sideflanges of the plates 10 which face upwardly flush with the top flanges0f the wall plates. T o fill the space between. the exterior andinterior frames, and surrounding the door opening thus formed, side doorplates ll'are secured to the side flanges of the plates of the interiorand exterior frames by means of clips 2 and a top door plate 12 issecured to the downwardlyvfaclug flanges of the horizontally arrangedplates 10 thereby forming a water-tight box around which the concretewill spread when poured, so that after the frames are removed. a dooropening having finished walls will be produced. Since the openings aremade in both the exterior and interior frames, it is manifest that freeaccess to the interior frame may be had at all times during theassembling of the same and also after the concrete has set to permit theplates forming the interior frame to be removed, which is essentialsince no access to the interior frame may be had from above or helow.

The window construction is somewhat similar and the opening for the sameis formed by utilizing short-length plates 13' in both the exterior andinterior frame which are secured and locked in place with their bottomsflush :with the bottoms of the standard wall plates.Horizontallygdisposed plates 14 are fastened to the exterior offsetplate 16.

18 is attached to the upper ends of the speside flanges of the standardplates of the exterior frame which face the opening are the top. andside reveal plates :1? having apertures therein alining with theapertures, in the flanges of the wall plates through which clips 2 arepassed. These .plates comprise right angle Ls whose free legs extendinwardly intothe wall space beyond' the surface of the plates of theexterior wall frame. as is shown in Figs.-2 and 4. A bottom reveal plate16 consisting of a T-shaped strip of iron is fastened to the upper endsof the short-length plates 13 of the exterior frame, which plates havesuitable apertures in their-top flanges for this purpose. Theup-standing leg of the T is offset from and lies in a plane outside ofthe surface plane of the wall plates 'to form the projecting window sillas will be later re ferred to. A wooden window frame '17, which is ofthe usual box frameconstruction, is secured to the free legs of the topand side reveal plates 15 by screws or other fastening means which frameis of such a width and thickness that it abuts the si1rfaces of theplates of the interior frame surrounding the window opening along itstop and side surfaces and extends down-' wardly to a point just belowthe top of the An L-shaped strip of iron cial plates 13 of the interiorframe against which the inner bottom edge of thewindow frame abuts. thuscompletely closing the opening between the interior frame and the windowframe. lhe space between the interior frame and the window frame isti'.--'are-' fore entirely closed, and the space between the exteriorframe and window fi'ai ie is closed along the top and sides of the fxameby the reveal plates 15 to which the frame is fastened. but since theT-shaped strip 16 is offset from the surface of the wall plates a space19 is left between the outer bottom edge of the window frame and theexterior frame through which access may be had to the concrete beneaththe window while the same is acing cast.

When the concrete is poured it will pack solidly around the top andsides of the window frame which, together with the reveal plates. formsa water-tight box preventing the flow of the concrete into the openingdesigned for the window, but since wet concrete is not particularlyfluid in its nature, the concrete will not pack around the bottom of thewindow frame and a shallow U- y shaped space will be left beneath thewindow into which the concrete will not flow. The space 19 permitsaccess to the concrete beneath the window and the workman may eitherstir the same bringing the concrete against the bottom of the windowframe, or additional concrete may be poured in so that the level of theconcrete will be brought up to the top edge of the free leg of the T-shaped strip 16. The concrete is then troweled off at a slight angleforming the Window sill, and since the free leg of the T- shaped piece16 is offset from the surface of the plates forming the exterior frames,the window sill will be integral with and offset from the wall of thehouse and thus add to the attractive appearanceof the same.

After the concrete has set the frame and reveal plates are removed andthe window frame will remain securely embedded in the concrete and thewindows may then be placed in position. A weather-strip 20 is preferablysecured to the bottom of the win-' dow frame which strip is embedded inthe concrete upon the casting of the same.
